Vibration screen special bearing 22330E1

This bearing is a vibration screen specific bearing 22330E1-XL

This bearing is a vibrating screen bearing produced for a mining equipment manufacturer in Henan in 2021.

The characteristics of this bearing mainly include strong load-bearing capacity, good impact resistance, high reliability, good lubrication performance, and the ability to overcome shaft deflection deformation. ‌

Vibration screen bearings are mainly used in mining vibration machinery equipment, vibration screen machinery, and vibration motors, and are one of the most critical components of such equipment. Due to its harsh working conditions, including high humidity, numerous dust particles, high rotational speed, high temperature, and strong vibration impact, the workload is extremely high. Therefore, the design and material selection of the vibrating screen bearings have been specially considered.

The material selection of this bearing is very particular, usually using special bearing steel, and the cage is made of machined brass, suitable for situations with eccentric loads to ensure performance and service life under high loads and strong vibrations.

This bearing has significant advantages compared to ordinary bearings. For example, the inner and outer rings, as well as the rolling elements, of the bearings for vibrating screens are made of vacuum degassed bearing steel, which has good fatigue resistance; The retaining frame is made of aluminum iron manganese bronze material, which has high strength, good elasticity, and better wear resistance. In addition, the design structure of the special bearings for vibrating screens has also been optimized, such as increasing the diameter and length of the rolling elements, and guiding the rollers with the outer ring edge of the cage, which greatly improves the bearing's load-bearing capacity and service life. In terms of manufacturing process, the vibration screen special bearings strictly follow high-precision standards, such as P6 level precision standards, to ensure the high performance and long service life of the bearings. Finally, the special bearings for vibrating screens have undergone special heat treatment, such as using a mixture of bainitic and martensitic quenching or martensitic quenching+high-temperature tempering for the inner and outer rings, to provide better impact resistance and vibration performance, ensuring stable operation in high temperature and strong vibration environments.
